＊1： The material of SNSI3T-M3 is TP270 (grade 1 titanium).
Application
Lighter-weight automobiles, aircrafts/aerospace equipment, robots, etc.FPD production equipment / Semiconductor manufacturing equipment / Electrical and electronic equipment / Offshore instruments / Plating facilities / General industrial equipment
Characteristics
- Titanium hex socket head cap screws with captive washers.
- Plain washers and spring washers are integrated into the screws, preventing concerns about fallout issues. (Washer abbreviation: I=3)
- When using a washer in spot facing, workability is improved because the bolt and washer can be mounted and removed at the same time.
- The specific gravity is approximately 60% that of stainless steel.
- Non-magnetic.
- Excellent chemical resistance / seawater resistance.
- Special chemical polishing and brightening treatment improve the quality of the surface. Additionally, products have been cleanroom washed and packed. Cleanroom specification prevents oil and dirt from adhering.⇒Cleanroom Wash / Cleanroom Packing Service
